1.安装nginx

yum install yum-priorities -y  wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm  rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm  yum install nginx

systemctl start nginx.service #启动nginx  systemctl stop nginx.service #停止  systemctl restart nginx.service #重启  systemctl enable nginx.service #设置开机启动

2.更改nginx端口号（根据自己需求）

cd /etc/nginx/conf.d/  vim default.conf  把listen 80改成listen 81<span><span>systemctl restart nginx.service </span><span class="comment">#重启nginx</span><span>  </span></span>

3.访问http://ip:81即可看到nginx首页

4.下一步安装php-fpm

yum install php-fpm <span><span>systemctl start php-fpm.service </span><span class="comment">#启动php-fpm</span><span></span></span><span>systemctl enable php-fpm.service <span class="comment">#设置开机启动</span><span>  </span></span><span></span>

5.更改nginx配置文件识别php （vi /etc/nginx/conf.d/default.conf，把之前的#给去掉），顺便改一下fastcgi_param

    location ~ \.php$ {          root           html;          fastcgi_pass   127.0.0.1:9000;          fastcgi_index  index.php;          fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name;          include        fastcgi_params;      }

6.测试nginx---

在 /usr/share/nginx/html中新建一个test.php <?php echo 123;?>

访问http://ip:81/test.php即可看到nginx中的text.php输出的内容

7.负载配置

    upstream site{              server 172.16.170.138;              server 172.16.170.139;      }      server {          listen       80;          server_name  localhost;                #charset koi8-r;          #access_log  /var/log/nginx/log/host.access.log  main;                location / {              root   /usr/share/nginx/html;              index  index.html index.htm;              proxy_pass http://site;          }
